avelength of light is 389.0 nm and its frequency is 7.707times 10^14 Hz. Show how this frequency value was calculated.

To calculate the frequency of light given its wavelength, we can use the formula: The speed of light in a vacuum is approximately meters per second (m/s).Given:- Wavelength ( ) = 389.0 nm- Speed of light ( ) = m/sFirst, we need to convert the wavelength from nanometers to meters: So, Now, we can calculate the frequency: Therefore, the frequency of the light with a wavelength of 389.0 nm is approximately Hz.
